Added MongoDB Destination, which uses Mongosis’ Connection Manager and the same C# driver, and has a limited support for nested documents. You can use dot notation (aa.bb.cc) in SSIS column names to describe nested documents. It inserts documents through C# driver’s InsertBatch method.

Also changed unit tests to use PrivateObject instead of accessors, because they aren't supported anymore in VS2012.

Version number changed to 1.8.1.
